SSSD now supports using `full_name_format=%1$s` to set the output name of AD trusted users to a shortname
Previously, in trust setups, certain System Security Services Daemon (SSSD) features required using the default value for the `full_name_format` option in the `/etc/sssd/sssd.conf` file. Using `full_name_format=%1$s` to set the output format of trusted Active Directory (AD) users to a shortname broke other functionality.
This update decouples the internal representation of a user name from the output format. You can now use `full_name_format=%1$s` without breaking other SSSD functionality.
Note that the input name must still be qualified, except for when the `default_domain_suffix` option is used in `sssd.conf`.
